I'm having some trouble building an app that gets data from a database to keep a log of files added to a website.
Most URLs are generated from a file ID and a time stamp, some of those URLs are missing in the database but they're quite easy to regenerate. There's another type of generated URL that includes a string that I can't figure out. I'd like to know if it is possible to generate them too.
These URLs look quite like this:

As you can see, it looks like hexadecimal for the first 8 characters, the middle section looks very similar, but I can't recognize a pattern here. I would like to point out that the dates are stored as epoch numerals, though the easy links have readable dates.
I'd appreciate any kind of information that could help me start figuring out this pattern.
